Graphics memory is generally classified into two major types: dedicated and shared.
Dedicated graphics memory is memory
that is exclusively used by the graphics system. Non-graphics
applications cannot access this type of memory. This is commonly
referred to as "on-board” or "local video memory” (i.e. close to the
graphics processing unit - GPU). However, it isn’t limited to on-board
memory and a portion of system memory can also be dedicated to the
graphics subsystem. It is exclusively owned by the graphics subsystem.
Shared system memory can be used by the graphics
subsystem when needed. It is often referred to as "non-local video
memory” (i.e. far from the GPU). The shared memory is available to other
subsystems or non-graphics applications when it is not being used by
the graphics subsystem. Thus, it is never guaranteed to be available for
graphics because it could already be in use.
Typical error message that you can have: 128 Mb non local video memory or more.
You can modify the memory usage of your graphics board in order to get a
maximum performance. GPU requires 128 MB for minimal performance (256
Mb optimal).
- Backup your current BIOS Settings.
- Now in the BIOS, modify the value for "non local video memory"
(resp. "shared memory") to 256 MB or higher. Attention: depending on
your BIOS, these values naming can be different (possible names of the
value: - AGP aperture).
WARNING: improper modification to BIOS can damage your computer. We can not assume liability or responsibility for bad settings.
